TROY - Police said they need the public's help as they try to find a registered sex offender who vanished.

Edward Schafer is a parolee who, city police said, failed to register as a sex offender in the city.

The 23-year-old served prison time for having sexual contact with a 13-year-old girl in 2011. The state's sex offender registry says Schafer overpowered the girl and attacked her.

The photo from the registry shows Schafer with a goatee but police said he may have shaved it. Schafer is a Level 3 sex offender, a classification that characterizes him as a high risk. He is also accused of violating parole.

If you think you have information about Schafer, you can call Troy police at 270-4423.
